(a) Alpha-diversity in patients’ stool microbiome, represented by the Shannon index and Chao-1 index, before induction (T0), during aplasia (T1) and after hematological recovery (T2). p < .05 is considered significant. (b) A subset of OTUs, grouped by family, with a raw count at least of 300 was kept. Bray-Curtis distance and UPGMA algorithm were used to perform pairwise distance between samples and hierarchical clustering, respectively. The heatmap highlighted a clustering of two groups dominated by Bifidobacteriaceae, Lachnospiraceae and Ruminococcaceae at T0 progressively replaced by Enterococcaceae or Enterobacteriaceae at T1 and T2.
